looking for the QUIETEST gears!?
my US gears got 100 miles of heat cycle/break in the first 4 or 5 days after install. drove home from the shop for 40 miles 1/2 street 1/2 freeway the first day.
then i went on my merry way chirping 2nd and 3rd
no sounds, no wear pattern or pitting or anything on the gears.
these are 4.10's

My breakin consists of being easy of the gears and heat cyling them twice.
Also, I haven't set up THOUSANDS of gear sets like you are implying you did. I've also never installed a gears into a Dana/Chrysler.

I dont follow or agree with the "500 mile" theory either.
And FWIW, a few thousand is not an implication, it is a fact. I guess you could say I have been doing them for a few years.... for various sanctioning bodies as well as the general consumer.

As an entry level performance lube, straight 140wt is the answer. Just the film pressure strength of increase from a 140wt oil is worth the $7 a quart. But dont skimp on some kind of Autozone/Pepboys/Kragen type of off the shelf oil either. Get a quality lube from those like Schaffer, Torco or LE.

ChicagoTransAm, if it howls "like nutz" it is probably too late as you will more than likely have an appreciable wear pattern on the gears already. A set of new gears would be in order for a complete fix.
